植入性除颤器已广泛用于治疗室性心动过速(VT)和预防心源性猝死(SCD),但其长期效果仍有争议。本文评价置入性除颤器防治顽固性VT和SCD的作用。 方法 1989年10月至1992年6月间共有107例患者植入配有心内膜除颤电极的第三代自动除颤器,治疗顽固性VT或预防SCD,其中男性86例,女性21例,年龄57±13岁。左室射血分数(LVEF)40±15％,心功能分
Implanted defibrillators have been widely used to treat ventricular tachycardia (VT) and prevent sudden cardiac death (SCD), but its long-term effects remain controversial. This article evaluates the role of implantable defibrillators in the management of intractable VT and SCD. Methods From October 1989 to June 1992, a total of 107 patients were implanted with a third-generation automatic defibrillator equipped with an endocardial defibrillation electrode to treat refractory VT or prevent SCD. There were 86 males and 21 females, Age 57 ± 13 years old. Left ventricular ejection fraction (LVEF) 40 ± 15%, cardiac function score
